The boundary layer equations of vanes of centrifugal pump in two-dimensional incompressible fluid are set up and the relevant quantities are analyzed in the paper.
建立了简化成二维定常不可压缩流体的离心泵叶片的边界层方程，并对相关量进行了分析。

The inlet to the pump is located near the center so that fluid returning from the radiator hits the pumpvanes.
泵的入口靠近中心，因而能使从散热器回来的液体流到水泵的叶片。叶片将水甩出，进入发动机。

There is great flow impact on the head of vanes at different condition, and it will affect the performance of pump system greatly, so the shape of the head of vanes should be improved.
